4.7.3.2.1 Keys
These settings allow additional keys to be configured which handle input functions. The following functions can
be assigned:
Function Description
Cursor Left key
Cursor Right key
Delete key
Backspace key
4.7.3.2.2 Tabulator
Moves the cursor one character to the left without altering input. This allows the cursor to
be moved back a few places to correct a mistake or add a forgotten letter.
Moves the cursor one character to the right without altering input. The cursor can be
moved to a maximum of one place beyond the last character entered.
Deletes the character to the right of the cursor and advances the remaining characters (to
the right) one step forward. No gap is left when this key is pressed.
This key should be used even if the cursor keys were configured.
Deletes the character to the left of the cursor and moves all remaining characters one
place to the left.
Using the tabulator key (tab), the cursor can move more than one character to the right. The number of
characters that the cursor moves when pressing the tab key can be set using Tab distance.
AutoTab Mode can also be selected as an alternative so that the cursor moves to the next word. In this case,
words consist of entities using the letters a−z in upper or lower case. All other characters are considered
separators.
4.7.3.2.3 Mode
Different modes can be more practical than others for data input depending on the type of input. The number
and type of available keys can also affect how information is entered.
The Edit Mode list offers the following possibilities:
Edit
Clear
Mode Meaning
Key−Dependent
Password
4.7.3.3 Connecting Variables
Introduction to Visual Components 2.3
In this mode, an input field is edited normally. If the content should be changed, then the
previous contents must first be deleted using the Delete and/or Backspace keys.
In this mode, the previously existing text is basically overwritten. Editing the old text is not
possible since it is deleted when the first key is pressed to enter new input in the active field.
This mode combines the two previous modes depending on the first key used when editing the
field.
If the first key pressed is a cursor key, then the appropriate cursor movement occurs and the
text is preserved. This behavior corresponds to Edit mode.
Otherwise, the text is completely replaced. This behavior corresponds to Clear mode.
Operation is the same as Clear mode except that characters entered (as well as the existing)
are not displayed on the screen.
In this way, the input of hidden passwords and similar data is possible without having to be
displayed on the screen.
Symbols to be displayed in place of actual entered characters can be set in Password char. An
asterisk (*) is used by default.
Connecting with the control application takes place by connecting the appropriate variables. The following
variables can be connected.
